(I work in a small shop that sells sunglasses, shoes, and backpacks; basically, it’s an accessory shop. We are having a buy-one-get-one sale on our backpacks, but it’s only on certain brands, so we have signs set up inside and outside of our store. Everything is clearly printed; there is no fine print because our store manager knows people don’t read the fine print on sale signs, so she makes the font size 48 so people can see it clearly)

Customer: “I saw that there was a buy-one-get-one 50% off sale; I’d like to get purchase these.”

(She hands me two backpacks; one is included in the sale but the other is not.)

Me: “Unfortunately, this backpack isn’t included in the sale, but the other one is. The brands that are included in this sale are—” *lists all the brands on the sign* “If you need help finding a backpack like this one here, I would be happy to help.”

Customer: “No, your sign says, ‘Buy One Get One 50% off on all backpacks.’ It doesn’t say which ones are and which ones aren’t; I would like this one for 50% off.”

(I take her over to the sign and point out which brands it says are on sale.)

Me: “See, miss? It says right here. Unfortunately, the one brand is not included.”

Customer: “Well, no wonder I didn’t see it. Stores like these need to stop putting stuff in the fine print.”

(The customer walks out.)

Manager: “If I made the font any bigger, there would have been a store banner, and even then she probably wouldn’t have read it.”
